Description

    BACKGROUND OF THE INVENTION
  • 1. Technical Field
  • The invention relates to a fabrication method of a lens substrate having an anti-fog film layer and a structure thereof, and more particularly, to a lens substrate comprising an anti-fog film layer formed with a predetermined configuration and a proper thickness (substantially between 0.1 mm and 0.3 mm) by cellulose acetate, and a lens (i.e., a substrate layer) formed by electroplating and combining with the anti-fog film layer to form the lens substrate, wherein an overall thickness of the lens substrate is substantially thinned, and predetermined anti-fog properties of the lens substrate are kept after repeated cleaning or wiping after long terms.
  • 2. Description of Related Art
  • For goggles or similar glasses that protect parts of the human face and eyes such as glasses or goggles used in skiing, motor-cross racing, biking, car driving, sports, and safety operations in industrial environment. Anti-fog films are combined on the lenses of such glasses to provide anti-fog properties when being worn, so as to protect parts of the human face and eyes and provide expected anti-fog properties during usage. There are many implementation types to provide such glasses with anti-fog properties, and the ultimate goal of which is to allow the lens substrate to have structures with safety and anti-fog applications.
  • A first conventional type that allows the lens substrate to have an anti-fog film layer is disclosed here (as shown in FIG. 1); the type includes immersing a lens 10 in a chemical agent (i.e., an anti-fog agent) for a predetermined time (or may be substituted by coating), and carrying out electroplating processes on the lens 10 after the immersion to firmly cover an anti-fog film 20 in the above on the lens 10. If superior anti-fog properties are desired for the lens substrate, the time of immersion should be extended so that the applied anti-fog agent may adhere better and the surface of the lens substrate may be thicker; after processing the above anti-fog coating, subsequent electroplating processes may result in bubbles on the surface of the lens substrate and cause the fraction of defective lens substrates to increase.
  • The above implementation type that allows the lens substrate to have an anti-fog film layer has the following disadvantages:
  • 1. If superior anti-fog properties are desired for the lens substrate, satisfactory electroplating processing may not be simultaneously achieved, unless the lens substrate only undergoes mere anti-fog agent application or mere electroplating coating; however, such practices result in complication of the processing, and relatively increase cost and reduce production speed, which are not acceptable for most customers.
  • 2. Such anti-fog coating adheres on the lens substrate by immersion, and the anti-fog properties of the subsequently cut lenses may gradually diminish as the wearer wipes the lenses, and thus the expected anti-fog properties of the lens surface may be lost.
  • A second conventional type that allows the lens substrate to have an anti-fog film layer is also disclosed here (as shown in FIG. 2); in this type, each lens 30 includes a basic lens 301 and an anti-fog lens 302, wherein a planar component with a predetermined configuration and a proper thickness is immersed in a chemical agent (i.e., an anti-fog agent) for a predetermined time for anti-fog processing, and the anti-fog lens 302 is formed (preferably substantially between 0.4 mm and 1.0 mm). A lens with a predetermined configuration and a proper thickness is subsequently processed by electroplating to form the basic lens 301; subsequently, the anti-fog lens 302 and the basic lens 301 use a peripheral foam 303 with a predetermined thickness and same periphery as a connection medium, wherein adhesives 304 adhere the two components (i.e., the anti-fog lens 302 and the basic lens 301) on the two sides of the peripheral foam 303, respectively, to form the lens 30. However, the curvatures of the two lenses (i.e., the anti-fog lens 302 and the basic lens 301) cannot be exactly the same, and thus the formed lens may easily cause the user to suffer from vertigo when wearing.
  • The above implementation type that allows the lens substrate to have an anti-fog film layer has the following disadvantages:
  • 1. Since the lens substrate includes a basic lens and an anti-fog lens using a peripheral foam as a connection medium, the product thickness of the formed lens substrate is rather large.
  • 2. After terms of usage, the foam between the basic lens and the anti-fog lens of the lens substrate may cause water to leak into between the two lenses from the outside as the user repeatedly washes the lens.
  • 3. The anti-fog coating on a side of the anti-fog lens of the lens substrate adheres on the predetermined lens by immersion, and the anti-fog properties of the subsequently cut lenses may gradually diminish as the wearer wipes the lenses, and thus the expected anti-fog properties of the lens surface may be lost.
  • The present invention seeks to substantially overcome the disadvantages of the implementation of the above similar conventional types that form lens substrates to have anti-fog film layers, so that a lens substrate comprises an anti-fog film layer formed with a predetermined configuration and a proper thickness (preferably substantially between 0.1 mm and 0.3 mm) by cellulose acetate, and a lens (i.e., a substrate layer) formed by electroplating and combining with the anti-fog film layer to form the lens substrate, wherein an overall thickness of the lens substrate is substantially thinned, and the anti-fog film layer on a side of the lens substrate has permanent anti-fog properties so that predetermined anti-fog properties of the lens substrate are kept after repeated cleaning or wiping after long terms.
    • BRIEF SUMMARY OF THE INVENTION
  • The present invention seeks to further improve the disadvantages of the implementation and usage of the conventional lens substrates formed to have anti-fog film layers, so that a lens substrate comprises an anti-fog film layer formed with a predetermined configuration and a proper thickness (substantially between 0.1 mm and 0.3 mm) by cellulose acetate, and a lens (i.e., a substrate layer) formed by electroplating and combining with the anti-fog film layer to form the lens substrate, wherein an overall thickness of the lens substrate is substantially thinned, and predetermined anti-fog properties of the lens substrate are kept after repeated cleaning or wiping after long terms.
